8.E.1.1 to 8.E.1.4

Which of the following is true of upwelling?

• It pushes hot water to the ocean floor and winds drag nutrients out to sea.

• The tide goes out to sea leaving tide pools with many animals that eaten by birds.

• Warm surface waters are blown off shore and cold deep water brings nutrients to the surface.

• Gases become dissolved into the ocean by wave action.

Which best explains why estuaries are an important habitat for many marine organisms in comparison to the open ocean?

• Estuaries have limited food.

• Estuaries contain more salt.

• Estuaries have more predators.

• Estuaries are rich in nutrients.

Estuaries are important because they:

• provide shelter for young organisms

• have LOTS of nutrients

• filter out pollution from the ocean

• all of the above

How does eutrophication cause the death of aquatic organisms

• the build up of carbon dioxide in the water

• the lack of nitrogen in the water

• the lack of carbon dioxide in the water

• the lack of oxygen in the water

In eutrophication, dissolved oxygen levels decrease because

• bacteria use it as they decompose organic material

• algae uses it during photosynthesis

• it reacts with hydrogen to form H2O (water)

• fish use it up as they consume algae

Which would most likely happen if too many nutrients entered an estuary?

• Nutrients would be used up by the fish and plants, keeping the estuary in balance.

• Algal blooms would lower dissolved oxygen levels, causing fish to suffocate.

• Algal blooms would decrease, leaving few food resources for fish.

• Nutrients would sink to the bottom, increasing soil deposition.

If a large amount of fertilizer enters a lake, which will most likely happen?
